Filter by:This is an observational study designed to monitor the course of the fraction of reticulated platelets and the correlation thereof to major adverse cardiac and cerebrovascular events after noncardiac surgery.
The purpose of this study is to assess safety and efficacy of Ticagrelor versus Clopidogrel in Asian/KOREAn patients with acute coronary syndromes intended for invasive management.
This study will be conducted in accordance with the local regulation of New Drug Application. Overall duration of this trial will be 3 years after approval of MFDS. Each subject will participate around 26 weeks, which include the 24 weeks treatment period and 2 weeks safety follow up period. Withdrawn subjects due to efficacy after 4 weeks treatment will participate in 6 weeks in total including 2 weeks safety follow up. Withdrawn subjects with other reason also have 2 weeks follow up period.
This study will be conducted in accordance with the local regulation of New Drug Application. Overall duration of this trial will be 3 years after approval of KFDA. Each subject will participate around 7 weeks, which include the 2 weeks Amlodipine run-in period, 4 weeks double blind period and 1 week safety follow up period
Previous studies have shown that interventions which modestly increase blood nitrite_ improve skeletal muscle function on exercise while sparing oxygen, and have been also shown to open up the blood flow during periods of oxygen deprivation. Inorganic nitrate in the diet is absorbed into the bloodstream, concentrated and reduced by bacteria in the mouth to nitrite, which is then absorbed into the bloodstream. . The purpose of this study is to look at the effects of oral inorganic nitrate supplementation on clinical markers of heart ischaemia and the frequency of angina.
In this study the investigators will use careful scientific blinding of patient and their subsequent healthcare staff so that the investigators can determine exactly how much difference coronary angioplasty makes to symptoms and blood supply to the heart. After the 6 weeks blinded phase, all patients will be unblinded and the patients who had undergone sham procedure will be offered the active therapy.
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
The purpose of this study is to evaluate whether new novel markers from the clinical electrocardiogram (EKG), which have been used as non-invasive measures of heart disease, can detect coronary artery disease in patients with chest pain. The researchers are especially interested in studying how changes in these unique waves evolve over time with rest and activity. It is hoped that the findings will be helpful in differentiating patients with cardiac chest pain at emergency departments from those with non-cardiac chest pain, as early identification can accelerate treatment and save lives. Eligible participants are those age 18 and older who have been referred for a nuclear stress test at University of Pittsburgh Medical Center Presbyterian Hospital to rule out coronary artery disease as part of their clinical care.
The purpose of this study is to determine the effectiveness of Ranolazine for the treatment chest pain from disease of small vessels of the heart also known as 'microvascular angina'.
Hypothesis: acupoint application is effective for managing chronic stable angina pectoris. Aim: to evaluate the efficacy and safety of acupoint application on the specific acupoints for chronic stable angina pectoris. Design: A Randomized, Controlled,Double Blind trial. 200 participants will be included. Four arms: herbal medicine application on acupoint group , placebo application on acupoint group , herbal medicine application on non-acupoint group and placebo application on non-acupoint group.
